Both "i.e." and "e.g." should always be followed by a comma.  (The
previous sentence is not self-contradictory because in these
instances, the terms are quoted rather than used.)  I am not able to
think of an example where this rule should not be applied, even though
on the internet it is commonly not followed.  They should always be 
preceded
by a comma when they do not start a sentence, an interjection, or a
parenthetical phrase.  Likewise, "etc." should always be preceded by a
comma unless a sentence is constructed that starts with "etc."
